HPS Performance Blue Cold Air Intake Kit Compatible for 2015-2017 Subaru WRX STI 2.5L Turbo Impreza, 837-573BL

Built for performance and show, the HPS Blue cold air intake kit relocates HPS Performance Air Filter outside of the engine compartment to deliver the coolest air inlet temperatures. Compare to the tradiational shortram air intake, HPS long ram cool air intake delivers cooler air with more oxygen, which translates into a more intense explosion in the vehicle combustion chamber to produce dyno proven performance gains +19.4 Whp horsepower, +20.5 Ft/lbs torque and improve throttle response while maintaining safe air fuel ratio. The heavy duty powder coated steel heat shield blocks off hot air from the engine compartment for the best cooling effect. The included installation instruction has clear pictures and description to guide the installer throughout the whole process. The kit does NOT require tuning and no modification is required. The included air straightener also minimize the chance of CEL light. HPS light weight mandrel-bent aluminum alloy piping replace the stock restrictive air box and optimize the air flow with long lasting durability. HPS cold air induction system features HPS signature race proven reinforced silicone hoses and industrial grade 100% stainless steel T-bolt clamps, which ensure the durability and reliability during the extreme driving condition. The All-New HPS Performance Air Filters are made in the United State and are designed with performance in mind, delivering excellent filtration without sacrificing air flow. Washable and reusable.
